Sorrow's Fall — Danielle Devor

Nothing like a mess that begins with demons… Jimmy has himself in a hell of a pickle-no pun intended. The Devil kidnapping Tabby was just the beginning. Now, his life was completely upside down and he needs to figure out how to save her-fast. But how do you get down to Hell without the Devil knowing? By summoning a demon, of course. Which puts Jimmy's status as a Marker for God in jeopardy. You can't be holy if you're summoning the damned. When Jimmy realizes that there is a planned coup of Hell, he knows he's run out of time. He must figure out how to get he and Tabby back to Earth without a hitch before they are damned for eternity.
